l3e it known that I, CHARLES S'rroirnnn, a citizen of theUnited States, anda resident of Philadelphia, county of Philadelphia,

State of Pennsylvania, have linvented a cersuch irons and to increase' the efficiency thereof.v My improvement will'be fully described hereinafter and the :features ofA novelty will be pointed out inthe appended claims. 1 Y Reference is to be had to the accompanying drawings lin which Figure lis a longitu-V dinal section of my improved sad iron; Fig. Q is a plan view thereof `with Athe cover'removed; Fig. 3 is'a horizontal section looking upward and taken on the line 3,-3 of Fig. 1; Figsfl and 5 are cross sections'ron the lines 4 4 and '5*5 respectively of Fig. 9;- Fig. 6 is a longitudinal section of another form of my improved sady iron; Fig. 7 is a plan view thereof with the eoverremoved; Fig. 8 is a similar view with burner removed from the body; andFigs. 9 and 10 are cross-v sections taken respectively on the lines 9 9 and 10-10 of Fig; 7.

. In the drawings 1 represents the body of the iron, said body being hollow and provided with a bottom preferably havingv an intermediate portion 2 which is relatively thicker than the adjacent end portions thereof and its rear edge preferably curved as in dicated'at 3 in Fig. 2." The upper edgesof the side walls of said body are formed with a plurality of recessesll which form outlets for the products of kcombustion'when the body is closed by meansof the cover 5. The latter may be `movably secured upony the body 1 in any suitable manner and' as illustrated is provided at its front end with an elongated opening 6 adapted to'receivea hook 7 projecting upwardly from the body at thev apex thereof, and arranged to extend overv the upper surface ofthe ,cover in a rearward direction. At its rear eind the said cover 5 is provided with arearwardly open slot 8 for'the accommodation of the shank or stem 9 when the partsy are in operative connection, said shank 'or vstern having a Specification vof Letters Patent.

and being ysecured to or forming part of ythe i locking lever 10. The lattery is vprovided with horizontal shoulders 11 and 11a adapted to be movedl over and into engagement with the upper surface of the cover as the lever l0 is'manip'ulated, that portion of the surfaceofsaid cover5'. whichV is adjacent to.

the slot 8 and adapted to beengaged'by the` shoulderl 11 being inclined `or curved. upwardlytoward thejfront of the iron inthe preferred construction vlas indicated at 12 in Figs. 1 and 6.- Thusthe lever 10 is moved inthe arc .of a circle to causethe: shoulders said shoulders, 11 and` 11a downwardly and rfinally firmly clamp the rear-v end Vofthe cover 5.on the 4body' 1. During `thisactua-` tion of thelocking lever 10 as described the shoulder 114 will'engage the inclined portion i 12' and will exert a camming action :thereon tending to force the said cover forward and beneath vthe hook 7 whereby the front end of said cover is securely locked in position. 1

With this arrangement both ends of thev cover are trmlysecured in operative connection with the body and the danger of locking the rear end-of said cover while the forward end thereof is unintentionallyL left .unsecured 1 is obviated. f

The cover 5 is of a Asize and shape to properly close the upwardly open body and at the same time to leave the` recesses l entirely lfree and unobstructedl for the escape of the combustion products. l

In'order/that the iron may be readily manipulated and the cover moved to and ,from its closed positionrelatively to the body 1.1 provide a handle 13 preferably constructed of wood or other material ywhich is a `poor conductor of heat and lcarried for instance by a support llof substantially U-shape as shown in Fig. 1. The saidsupport let may be connected'with thecover 5'` in any suitable manner as for instance by means of a single screw 15 extending through said support into 'a boss V16V formed kon s aidy cover and which in laddition servesL to lspacefsaid support 'from the coverand thus.kk reduces inclusive in combinationwith the body conlprises a hollow chamber or shell 18 adapted forconnection with a source of fue'lsupply through'the medium of' the customary Bunsen tube 19 provided with theusual nippler 20' for the accommodation of the well known flexible tube or hose. The Bunsen tube 19 isipreferably detachably connected with the shell 18 inorder to facilitate the lassembling of the Vparts and extends through a suitable, opening 21 in the rear wall of the body. The vforward end of the shell 1S extends transversely across the longitiulinal axis of the'body 1. and is `covered by means of a plate 22 detachably secured in position in any suitablemanner as by-means of a screw 23 connected with a bridge piece 23 extend-v ing vertically across the shell 1S7` said plate 22 being provided with jet `apertures 211 which project toward the front or apex of the'iron. The frontend of the shell is inclined so that the plate 22 when in position to cover the saine will be disposed at an acute angle relatively to the bottom of thel body 1 with the result that the jet aportures 24 will always be directed'toward the inner surface of the said bottom of the iron. A pair of members 25 curved to substantially fit along the inner surfaces of the side walls of the body 1 extend forwardly from the shell 18 and are connected together at their front ends by ineansof a transverse plate 26, the shell 18, members 25 and plate 26 beingtpreferably castor-otherwise constructed in one piece to form ali-intermediate space27. 1n the operative conditionsr of the iron the plate 2.6 rests upon lugs' 28 formed on the inner surfaces ofthe side walls whoreby the forward'end of the burner is supported in positionrthc rear end-thereofbeing supported bythe Bunsen `tube 19 as shown in Fig. 1. 'The plate 2G is provided with an elongated slot 29 through whichthe shank of a screw 30 is arranged to extend into screw threaded engagement lwith a projection 31y projecting upwardly from' the bottom of the iron, the head of' said screw being arranged to bear upon said plate v26 lwhereby said forward end of the'burner is securelyfastened in operative position. rthe elongated slot 29 permits an adjustment of the burner in a lengthwise direction vto seineens@ cure a proper cooperation between the parts at 'all times. 1 rlhe projection' '3.11 is'A pointed or Ywedge shapedtowardlthe rear of thebody for the purpose of reducing resistance to 'the travel of the heat toward the front of is brought toa closed position afterignition` has taken place. After being ignited the flames'will be directed toward the apex and bottom of the ironv owing to the direction -in which said apertures extend and the inclination .of the plate 22 and front lend of-'the shell 18 andwill contact with thefrelatively thickened portion 2 of the bottom of the iron. This ythickened portion 2 takes longer to heat than vthe adjacent thinner parts -of said bottom which areat adistance from the flames and by conduction heats said thinner parts so thatan operative'and ef fective degree of heat is produced*Y inail parts of the bottom at approximately -the same time and the said bottom is evenly heated throughout its entire extent.

1n order to confine the heat in close prox imity to the bottom ofthe iron and to prevent same from escaping upwardly through the space 27 I provide a closure 32which is adapted to fit or set into saidspace fand as shown preferably depends from the cover 5 so that when the latter is in'its -closed position the closure 32 willbe located in'said space 27 and completelyvfill the same. The rear wall of said closure 32 is; preferably beveled vertically and curved laterally tto lit a correspondingly shaped portion of the shell 18 as shownin `Figs. 1 and 3'. The said closure may be secured to the cover in any suitable manner as by means of a nut 15 fitted upon'the end of the screwl which .in this case projects through the cover and through said closure S21-which latter may be provided with a recess for the reception of said nut 15a to secure a flush construction. lVith this arrangement a complete surface vis formed in front offthe burner Vshell 18 whereby the heatrgenerated. by the flamesV at the jet apertures 24V is confined in close proximity to the bottomof'theiron and thus exerts a heating `e`ffect-.thereon n a Y maximumly effective manner. VIn the above construction the products of combus foo izo

tion pass along the bottom beneath the suriso and closure 32 over the entire bottom toward the front ofthe iron and out through the space a between the-forward end'of the burner and the apex of the iron andfinally escape to the atmosphere through the recesses 4. The air necessary to `promote and sustain combustion is drawn into the body through the rearmost recesses lf andpasses to the flamesat the jet apertures through the spacesV b betweenfthe shell`18- andthe walls of the' body 1. necessity for special inlets fortheair is done away withand the cost of 4manufacture of the `iron as a whole is materiallyV reducedl without affecting its eiiiciency'. The said clo-` sure in addition to the Vfunc'tionsldescribedl may also be utilized lto add weight-#to the iron and by being detachablyfsecured Ato -the cover may Aberepl'acedby other clo-y sures so that the Vweight of the-iron may in this manner be` readily adjustedv to vmeet` different circumstances. VBy' detachably con-H necting the plate 22 with the 'shell 18 the said plate may be replaced by others having jet'apertures of different sizes or-inv dierent terior vof the shell 18 to be easilyV cleaned from time to time whereby the said burner:

may at all times be maintained ina condition of maximum efficiency;y YThe bridge piece 23a serves to break the force of the fuel coming from thetube 19 and divides the same and distributes it in the shell' 18 whereby said fuel is preventedfrom directly rushing through the jet apertures'24 thus making the burner substantially noiseless and obviating waste of fuel. The burner may be readily removed fromthe body-by simply first disconnecting the Bunsen tube 19 therefrom and then removing the screw 30 after lwhich said burner is .freetof be lifted from said body 1:. for any purpo'sej This form of my improved 'burneris ex# tremely light in weight 'and'comprises no intricateparts likely -to become disarranged.' As shownlin lFigsu to'10 inclusive the front end or apeX 1a of the hollow'body 1' preferably inclines rearwardly and the 'side walls' l1b thereof preferably! converge up-y wardly as illustrated in' Figs.' fandb. VIn this vformv the upper edges ofI saidv sidewalls 1b are cut away to form Icontinuous 'recesses La which extend:lengthwiseof said/body 1, said sidewalls 1b being'otherwise preferably entirely smooth and unbroken as in `the `first form of my improvement. vThe rear edge of the bottom iny this form of illy-'improvediron` may also be curved'as at Sin the form first described.

In the form at present,A being` described the'cover 5a is provided with two.,}j referaV bly yintegral and spaced lugs VV17a .projectingV upwardly and having their free end por-k tions reduced 'in diameter and arranged 'to extend into correspondingly located sockets in the lsupport 111C?, which consequentlyrests upon the shoulders formed by the largestk support A14e from rotating in aplaneparal-T lel with the surface plane of the'cover or in other words "from swinging about the screw k15. asian axis andfalso lser-ve to main: tain said support substantially outof con.- tact `withnthe cover i proper and thus igedU-,Ge

When it is desired lto use this forni .of iron, it is .connected -with =a source of fuel supply 'in the same vwayas described ,with

regard -to the lforni .of ,my v.improvement yfirst described. "The-'fuel' passes through thge tube 191into theshell or burner chamber 18a and outthrough the aperturesQA@L wljiere it-may be ignited in any suitable manner asfby passing a lighted match, taperer .other jigniting :medium :through the. opening 137.' ".llhis opening '37 may -.be .omitted if desired vand the fuel simplygpermittedtofenter the body 1 `.for a short period and Vthen ignited .either the space a or the spaces 26a. `After .being ignited the Vflames at the jet apertures Qla will loe-directed toward the apexand bottomr owing to the direction lin ywhich .said apertures project and the inclination ofthe wall 1Sb :and `may .even be deflected `toward said fbottom by the -plate 25a, which latter serves .to confinethe -heat from saidv flames in close proximity to `said bottom` and thus prevents `indiscriminate spreading .and loss of said heatand in consequence insures a rapid heating of the iron `and themaintenance of said heated condition throughout the period of use of saidiron. Y:Iffthe air inlets 34 form part ofthe structure airrwill pass through the same to the flamesat .the burner it has'gbeen .found howeyerthat these roo ' air inlets are not absolutely necessary and that a sufficient amount of air will pass through the recesses l, and spaces a and 26L and even through the opening 37, if this is used, to said flames. Substantially perfect combustion is secured in either case without the need of any additional air inlets. By rotating the screw 85 the inclination of the plate 25a relatively to the bottom of the iron is adjusted'to bring the lugs 25h into engagement with the side Walls lb whereby said plate, the shell or burner chamber 18 and the tube 19 are firmly secured in position. The said plate 25 thus confines the heat inthe space beneath it and also directs said heat along the bottom so that all parts thereof will be directly influenced thereby. It will be noted that the front face of the burner is preferably flat vand of considerable extent in both forms of my invention so that a burner having a maximum heating action is secured and jets or flames of maximum effect are provided. It will further be seen that in the form of my improvement illustrated in Figs. 6 to 10 inclusive the lugs 25" through contact with the inner surfaces of the upwardly converging side walls 1b at a certain point limit the upward adjustment of the plate 25a and prevent excessive actuation of the screw 35 and complete removal of the forward end of said plate from the body.

The burner and its connected parts in said last form may be readily removed from the body when this is desired, by simply first removing the cover 5a, then disconnecting the tube 19 and then tilting one longitudinal edge upwardly, in -which condition said burner and its parts are easily taken from the said body.

It will further be apparent that the members 25 and plate 26 may be combined with the shell 18a of Fig. 6 or that the plate 25a and screw 35 of said Fig. 6 may be come' bined with the shell 18 of Fig. 1. The projections 33 and air channels 34 may also be introduced into the form of my improvement first described if this should be desired or found advisable.

It will be seen that in both forms my iron is extremely simple in construction, the body thereof being merely an upwardly open shell absolutely unbroken except for the upper recesses 4 and la and adapted to removably and adjustably receive the burner which itself is extremely simple in construction in both forms. An iron constructed in accordance with either form of the present invention will operate in a maximumly effective manner and may be easily adjusted to so operate under all conditions and with all, grades of gaseous fuel. A

By curving the rear edge of the bottom of the iron as shown at 3 Ythe said edge may be introduced into folds or creases and the body of the iron oscillated by means of the handle thus facilitating the ironing of the fabric beneath such folds or in the creases, the curved edge 3 rolling along said folds or creases as it were during this operation.

Various changes in the specific form shown and described may be made within the scopeof the claims without departing from the spirit of my invention.

I claim a 1. A self-heating sad iron comprising a hollow body, a burner therein `having an apertured face extending transversely to the longitudinal axis of said body, a pair of connected members extending from said burner for supportingsame and forming a substantially horizontal opening in front of said apertured face, a movable cover for said body and a closure carried by said cover'and arranged vto fit in said opening whereby the heat from the burner is confined adjacent to the bottom of said body.

2. .A self-heating sad iron comprising a hollow body, lugs in said body near the apex thereof, a projection vextending upwardly from said body and converging toward the rear thereof, a cover for said body, a burner in said body having an apertured face extending transversely to the longitudinal axis thereof, members extending from said burner parallel with the side walls of said body and arranged to rest upon said lugs whereby said burner is supported in position, a plate connecting the free ends of said members and provided with a slot, a screw extending through lsaid slot into engagement with said projection whereby said burner is secured against removal from said body,said inembers and plate forming a substantially horizontal opening in front of said apertured plate, and a closure depending from said' witnesses. 1
